ROEE-SOCKET FOR WELL-TOOLS.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed November 27, 1915. Serial No. 63,862.

To all whom it may concern:

Be it known that I, JACOB H. VVILT, acitizen of the United States, residing at Toledo,

a jar rope socket and swivel plunger, which may be used to connect a drill rope with a well tool.

The primary object of the invention is to provide a rope socket of the class de scribed which, when applied to a well tool may be used to connect either a Manila drill cable, or a wire cable, with the well tool.

Another object of the invention is to provide a device of the class described in which a plunger may be retained in the tool holder, or a rope socket retained in the plunger, without using threaded couplings, bolts or the like, thus avoiding any possibility of the parts becoming disconnected while the device is in use.

A further object of the invention is to provide the rope socket with a swivel plunger which normally serves as a socket for the Manila cable and has a centrally disposed bore therein, in which may be removably mounted a socket member, for the reception of a wire cable thus adapting the device for use in connection witheither a Manila drill cable, or wire cableas the occasion may require.

A still further object of the invention is to provide the tool holder which serves as a casing for the swivel plunger with novel means for retaining the plunger within the tool holder, said means coacting with the sleeve to limit the sliding movement of the plunger within the tool holder in one direction. c

Another object of the invention is to pro vide a plunger for the device having a centrally disposed bore therein which coacts with a reduced portion on the socket member for connectionwith a wire rope, to provide a chamber within the plunger for the reception of fusible material, for holding the socket member within the plunger, so that the socket member may be removed from the plunger when the occasion requires without the necessity of removing the plunger from the tool holder.

with these and other objects in view the invention resides in the novel combination and arrangement of parts which will be hereinafter described and more particularly pointed out in the claims. i

The preferred embodiment of the invention has been illustrated in the accompanying drawings, although no restriction is necessarily made to the precise details of construction therein shown, as changes, al-

terations and modifications within the scope of the appended claims may be resorted to I when so desired.

Like characters of reference denote corresponding parts throughout the several views in the drawings in which,

Figure l is a side elevation of a rope socket for well tools constructed in accordance with the invention, Fig. 2 is a vertical transverse sectional view taken on the line :22 of Fig. 1, Fig. 3 is a view similar to Fig. 2 showing the socket member for engagement with a wire cable removed from the plunger of the device and a portion of a Manila drill cable secured in said plunger,

Fig. 4: is a horizontal transverse sectional view on the line H of Fig. 2, Fig. 5 is a view similar to Fig.4 taken on the line 5-5 of Fig. 2, Fig. 6 is a sectional view taken on the line 6-6 of Fig.3.

Referring now to the. drawings in detail the numeral 1 designates the rope socket as a whole which, comprises a casingor tool holder, 2 in which is mounted a plunger 3 adapted for the reception of-a socket member l. j

The tool holder 2 which is cylindrical in shape is provided at one end with a threaded opening 5 adapted to receive'a well tool not shown in the drawings. The tool. holder 2 has extending centrally thereof for the greater portion of its length a bore. 6, said,

rugations 9 for a purpose which will be hereinafter described. The bore 6 has a portion thereof adjacent its lower end reduced, as indicated by the numeral to provide a seat 11. Arranged at diametrically opposite points in the tool holder 2 above and below the reduced or, enlarged portion of the bore 6 are openings 12, which,

c'oact with similar openlngs 13 communicating with the reduced portion of the bore 6 at the lower end thereof to provide inlet and outlet ports for fluid oriother foreign matter which may gain access to the interior of the bore 6 while the tool holder is in use. An opening 14 is formed in the tool holder 2 andcommunicates with the interior of the bore 6 between the enlarged and reduced portion there of.

Mounted in the bore6 of the tool holder 7 2 for sliding and rotary movement is the plunger 3, said plunger having an enlarged portion 15 between the endsthereof of less 7 length than the distancebetween'the enlarged portion 7 and the reduced portion 10 ofthe bore, said enlargement providing shoulders 15 and 16 on the plunger 3. The plunger 3 is also provided with a centrally disposed bore 17 enlarged between the ends, as indicated by the numeral 18 and has cominunicating therewith an opening 19 opening outthroughthe peripheral wall of the plunger 3. V p

A sleeve 20 is disposed in'the enlarged portion of the bore 6 and has one end thereof resting upon theshoulder8- to limit the downward movement of the sleeve within the bore 6. The sleeve 20 is provided with an. annular beveled portion adjacent the portion thereof adapted to contact with the shoulder 8 as indicated by the numeral 21, said beveled portion providing a seat against which the shoulder 16 on the plunger is adapted contact upon upward movement of the plunger "within the tool holder. The upper por'tion'o'fthe sleeve 20, is reduced and provided with circular corrugations 22 similar to the corrugations 9 and registering therewith to provide a chamber 23 in the upper portion of the tool holder 2 for the receptionof suitable fusible material, indi cated by the numeral 24. Threadedly enga'gediwith the upper end of the tool holder 7 2 and inclosing the open end of the chamber openings 27 .23 is a cap 25, said cap having a centrally disposed opening 26 through which loosely f passes" one endof the'plunger 3, while arranged concentrically about said opening andcommunicating with the chamber 23 are Disposed in the bore 17 in the plunger 3 'is the socket member 4:, said socket member being provided with a centrally disposed channel 28 having a flared'portion 29 at the lower end of said channel to receive the knotted end of the wire cable when passed "therethrough. The socket 'member 4; is reduced between its ends, as indicated by the r the sleeve 20.

position the bolt or pin 32 is passed through cap 25 while in a molten state.

numeral 30, said reduced portion being adapted to register with the enlargement 18 in the bore 17 and coact therewith to provide a chamber for the reception of fusible material for maintaining the socket member within the'plunger 3 as indicated by the numeral 31.

Referring now'to Fig. 3 in the drawing it will be seen that when the rope socket and swivelplunger are used to connect the end of the Manila drill cable with the well tool the cable can be disconnected from the rope socket in the following manner: The plunger 3 is first moved in an upward direction till the shoulder 16 contacts with the seat 21 on With the plunger in this of the cable to be withdrawn from the bore in the plunger. It will of course be understood that when it is desired to connect the Manila drill cable with the toolholder the above mentioned operation is reversed and that when the bolt 32 has been withdravm from the tool holder the device is ready for use.

If forany reason it should be necessary to remove the plunger with the end of the Manila drill cable the end of the tool holder containing the fusible material is heated and held in a position to enable saidmateria'l toescape through the openings 27 in the After this has been accomplished the cap 25 may be removed from the end of the tool hdldcr and the plunger to which the drill cable is attached removed therefrom.

l/Vhen it is desired to connect the end of the wire drill cable with the tool holder the 7 end of the Manila cable is removed from the the end of the wire cable passed through the socket member 4 and knotted. The" socket ,member is now positioned injtheplunger and fusible material poured"through the openlngs 14E and19 intojthe tool holder till the chamber formed by the enlargementsof plunger in the manner first described and v the bore in the plunger and the reduced 3 portions n the socket member is filledas f clearly illustrated in Fig.2 in the drawings.

From the foregoing statement it willbe seen that the socket member will be securely held withinthe plunger and that when it is I I necessary to remove the socket member from the plunger the heat applied to the tool holder will soften the fusible material 31 and allow the same to escape through the openings 14 and 19.

From the above described construction it will be at once apparent that the socket member can at any time be removed from the plunger Without disconnecting the plunger from the tool holder thus adapting the device to be advantageously used in connection with either a wire drill cable or a Manila drill cable as occasion may require.

Having thus described the invention what is claimed as new is 1. A device of the class described, comprising a casing having a longitudinally extending bore, a sleeve removably mounted in said bore, means for retaining the sleeve within the casing disposed between said sleeve and casing, a plunger mounted to slide and turn in said bore and sleeve and having a centrally disposed channel, and a socket member removably mounted in said plunger.

2. A device of the class described comprising a casing having a longitudinally extending bore, a plunger mounted to turn and slide in said bore, a sleeve disposed in said bore for limiting the sliding movement of said plunger in one direction, fusible material interposed between said sleeve and easing, a socket member disposed in said plunger and provided with a centrally arranged channel providing a rope socket, and means for retaining the socket member within the plunger.

3. A device of the class described comprising a casing having a longitudinally extending bore, a plunger mounted to turn and slide in said bore, a shoulder formed in said bore for limiting the sliding movement of the plunger in one direction, a sleeve disposed in the path of movement of the plunger above said shoulder and removably connected with the casing, a socket member extending longitudinally of the plunger and provided with a reduced portion, and means for retaining said socket member Within the plunger interposed between the reduced portion on the socket member and the plunger.
